conventional engine

GTRE have a MoU with Russia for adding their universal thrust vectoring to Kaveri. As of today, not even a single test for this is done. Ok, atleast till 2016 Dec.

Russia will never let India master engine technology. Mark my words.

GTRE is still betting on France to pull through. Even this is a sham. As I understood, France will replace the faulty Indian core with theirs and viola, engine done.

I am not sure how India will hold the IP.

China consolidated their engine tech companies, put a road map for their applications, pumped money( this included hiring former soviet bloc engineers). WS10 is their first modern tech engine. And now they are making derivatives.
